Hi Charles:
I am not sure of the cause of your problem. My advice would be to concentrate on playback first, then try to get recording working. Are you using Windows 3.1 or Windows 95? What device drivers are listed in the "available devices" box in the NWC MIDI tab of Options? Are you using both a sound card and a separate MIDI card? If so, there may be IRQ conflicts between the two. In general, I suggest trying one device at a time in the NWC "Devices used by playback" list, and see if you can get one of them to play back to your external keyboard. I can confirm that, when set up properly, NWC willl happily send and recive MIDI events to an external device. May users are now taking advantage of this. The trick is to get your system configured properly.
I hope this helps.
